Hello everyone I have meeted a problem with linux kernel 2.6.X.X that my user app wants to get thread kernel stack frame ponter(FP) from user space by system call or /proc system or any other ways except driver. I do not want to write a driver,) to steal FP from kernel. I have tried to use ptrace syscall to get FP with command PTRACE_GETREGS, but It returns only user stack FP rather than kernel stack fp. would anyone please to give me a hint to solve the problem. thanks a lot. regards Bob Wang -- To unsubscribe from this list: send the line "unsubscribe linux-apps" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
